【Abstract】 According to prediction theory,the asymptotic wind speed changes in time series prediction model is proposed.The future wind speed datas are predicted by using existing datas.In this paper,and the finite element model of the structure is established.The natural frequencies and mode shapes of the structure are obtained by wind speed time-history analysis.By analyzing the dynamic property of the structure,the rigidity feature and the weak link are found.The method in this paper has reference value in research of anti-wind.更多还原
